Ourinvention relates to apparatus for disl charging, out of the path ofthe incoming strip, the waste ends, generally referred to as crop ends,which are produced by cutting ofi' the .rough ends of lengths of metalstrip as they emerge from a rolling mill or the like. 1

The ends of ymetal strip, as originally produced in a rolling mill, arerough, and it is common practice to cut them off. In many instances thisgives rise to a aieed for getting the,cropped end out ofthe way of theonf coming strip. As one example,where the strip comes from the rollingmill to a fiyi'ng cutter, or like device, by which it is cut intolengths as it progresses forward, and

is then passed on to a roller table or equivalent means for rec'eiving1t, theA rough leading y end is first cutoff', and it is desirable toget this cropped end out of the way of the eut length which immediatelyfollows it forward. It is the-principal object of our nvention toprovide an apparatus by means of which this can be accomplished easilyand quickly, and which will be'simple of construction and convenient touse.

A discharging apparatus constructed in accordance wit-h our invention isdescribed, by way of example, in the following specification, and shownin the accompanying drawings, as associated with va flying cutter forcutting strip into lengths as it emerges from a. rolling mill, though itwill be understood that the invention has usefulness in connection withnumerous other forms of installation in which it is desirable thatmaterial be discharged. A

In the drawings:

Fig. 1 is a plan, with the blade of the flying cutter removed; l

Fig. 2 is a side elevation; and

Fig. 3 is a section on the line III-III of Fig. 1, looking in thedirection of the arrows.

Referring now to these drawings, 10 designates a. framework carryingdriven rolls 11 which continuously feed forward the metallic strip a,the latter being guided by adjustable side guides 12 and 13. Theprogressing strip (L passes onto an anvil roll 14 with which cooperatesthe blade 15 of a flying cutter, the

Adjustably mounted, to correspondwith the adjustment of the side guides12, upon the framework of the fiying cutter 15, at the discharge side ofthe anvil roll 14, is a rail 16, disposed longitudinally in thedirection of travel of the strip. This rail supports, at one side, theissuing lengths of strip and, further, when a waste end (indicated Aatb) is cut ofl' koperates to support one side of such crop end as thelatter issues under its own momentum from the flying cutter, it beingunderstood that the operation is rapid, a strip yspeed of 900 feet perminute being ordinary. The other side of the crop end is unsupported,and thus the leading end of this side (the upper right-hand corner ofthis table is a rela l wards the flying cutter, and adapted to receiveand support the sides of the cut lengths of strip opposite to thosewhich are received and supported bythe short rail 18, is an adjustable,relatively long receiving rail 19. The rails 18 and 19 are curveddownward at their ends, as shown in Fig. 2, so as to prevent any) chanceof the ends of the out 0H lengths of strip drooping down and passingbeneath instead of above the rails. The under sides of the rails 18 and19 are formed with inclined edges 18a and 19a respectively.

Then the rough leading end of the strip is cut off, the upper right-handcorner (as seen in Fig. 1) of the crop end b drops downward, as referredlto above, and passes beneath the rail 19 as the crop end emerges, underits momentum, fro-m the flying cutter. Since the ends of ,the rails 16and 18 are relatively as into a receptaclel where the ends canaccumulate conveniently for removal. To direct the trailing corner ofthe crop end as it falls onto the chute 20, an inclined plate 22 issecured to the framework of the flying cutter, beside the rail 16. Thisplate 22 is con'- venie-nt-ly made removable so that, if desired,different sizes of plate can be used according to. different adjustmentsof ythe rail 16.

The ordinary cut pieces of strip, being in lengths greater than that ofthe crop ends, are supported, at the side opposite to lthe rail 16, byreason of their connection with the main body of the strip until theirleading edges reach, or nearly reach, the receiving rails 18 and 19, thedownwardly curved ends of these-rails looking after any such slightdrooping as may occur. Thus these pieces r pass over the rails 18 and 19and into the receiving roller table 17.

Our invention, therefore, by an apparatus of exceptionally simpleconstruction and great ease of adjustment, enables the crop ends to bedeflected out of the path of the issuing strip and to be discharged andcollected in a manner convenient for .subsequent removal.l

l/Ve claim:

1. The combination with adevice for cutting strip material in motion, ofa member* for receivingand supporting one edge portion of the advancingend of the material, said member being spaced from` said device, andmeans associated with said device for supporting the opposite edgeportion only of said material as it issuesfrom said device, wherebyrelatively long pieces of material will pass onto ysaid receiving memberbut relatively short pieces will drop down'at one edge portion so as topass beneath the same.

2. The combination with a device for cutting strip material inmotion,vof a member for receiving and supporting'one edge portion oftheadvancing end of the material, said member being spaced from saiddevice, a second member for receiving and supporting the opposite edgeportion ofthe advancing end of the material, said second-named memberbeing spaced from said device by a greatn er distance than saidfirst-named member,

and means disposed substantially opposite said second-named member forsupporting said material as it issues from said device,

vice, and means associated with said device for supporting the oppositeedge portion of said material as it issues from said device, wherebyrelatively long pieces of material will pass onto said receiving memberbut relatively shortpieces will drop down at one edge portion so as topassbeneath the same and fall into said chute.

4. The combination withv a device for cutting strip material in motion,of a member for receiving and supporting one edge portion of theadvancing end of the material, said member being spaced from said deviceand having an inclined portion beneath the same, a second member forreceiving and supporting the opposite edge portion of the advancing endof the' material, said secondnamed member being spaced from said deviceby a greater distance than said firstnamed member, and means disposedsubstantially opposite said second-named member for supporting saidmaterial as it issues from said device, whereby relatively long piecesof material will pass onto said receiving members but the corners ofrelatively short pieces will pass beneath said first-named member and bedeflected downward by the inclined portion thereot1 so ,as to cause theopposite corners to pass beneath said second-named member.

In testimony whereof, we hereunto sign our names. y
